To all whom it may concern:

Be it known that I, LLOYD a citizen of the United States, residing at Burlington, in the county of Gofiey and State of Kansas, have invented a new and useful Shocking-Machine, of which the following is a specification.

This invention relates to machines for forming shocks and is more particularly an improvement upon the structure disclosed inmy patent issued on January 26, 1915, No..1,126,604.. r

One of the objects of the invention is to provide a shocking machine of the general type disclosedin my patent, before mentioned but which machine haslimproved means under thecontrol of the bundles being delivered to the shock former, for plac ing the twisting or tying mechanism into operative connection .Wlth its drlvlng means.

Another object of the invention is to provide simple and eflicient means for packing the bundles within the shock former where they are subjected to the action of the tying mechanism.

A further object is to provide meanswhereby the shock is ejected from the shock former so that the butt end of the shock will be forcibly shifted downwardly into engagement with the ground.

Another object of the invention is to pro*' vide shock forming and releasing means of improved form with which cooperates a locking mechanism constituting efficient means for holding said shock support in active position.

I With the foregoing and other objects in view which will. appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the,

invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings, thepreferred form of the invention has been shown.

In said drawings-Figure 1 is a front elevation of a shock former embodying the present invention. Fig. 2 is a top plan view thereof. Fig. 3 is an enlarged elevation of the packing and twisting or tying mechanism. Fig. 4 is a plan view of the twisting spiral and adjacent parts. Fig. 5

A. WILLIAMS,

is a plan view of one corner portionof the downwardly yieldable shock supporting means. Fig. 6 is a section on line AB Fig. 5.. Fig. 7 is a rear elevation of. the

structure shown'in Figs. 5 and 6, parts being broken away. Fig. 8 is a plan view of a portion of the shock support, one of the guides adjacent thereto being shown in sec tion. Fig. 9 is a section online C-D Fig. 3."

Referring to the figures by characters of reference, 1 designates the base frame of the shock former open at its back and having asupportingcaster connected to the front portion thereof, as shown at 2. g

The base framehas standards 3 extending upwardly from the inner sides thereof and preferably formedjof'angle strips as shown particularly, in Fig. 8, these standards' constituting guide rails'as'hereinafter set forth.

Angle strips 3' form connections between i the standards and one of them may be provided with brackets l-constituting bearings for the upper shaft 5 of an endless elevator '6. This elevator is preferably formed of chains mounted on sprockets 7 secured to the shaft 5, said chains having outstanding fingers 8 and being also mounted onsprockets 9 secured to a shaft 10 which is journaled within the lower portion of an extension frame 11 supported beyond the side of the base frame 1. A main drive wheel 12 is arranged between base frame'l and extension frame 11 and a sprocket wheel 13 rotates therewith.

Standards 14 extend from the lower ends of the extension frame 11 and are provided,

at their lower ends, with laterally extending. brackets 15 adapted to be connected, as by.

means of suitable couplings 16, to a part of a harvester not shown. These brackets support guides 17 which liefclose to the path of the fingers 8 and are adapted to be engaged by the chains of the elevator 6 which are extended forward. to sprockets 9 to form a table designed to receive bundles as they are ejected from the harvester and binder.

Reinforcing rails 18 extend upwardly from the standards 14. and along lines substantially parallel with the extension frame.

11, these rails being preferably-attached to the standards 8 and merging into, arches 19 which overhang the base frame 1 and merge into or are secured to other standards 20 which extend upwardly from the outer side of the base frame 1. Strips 21 connect the a he ngq ods 22mm be s a.

larly relative to the bracket 35.

cured to the connecting strips and be eX- tended downwardly between the outer standards 20. The space between the arches 19 and the uppermost portion of the elevator constitutes a throat through which bundles are delivered from the elevator and into the shock former made up of the base frame 1, standards 3 and 20 and arches 19.

A front strip 23 is connected to the arches 19 and has depending spring fingers 24 supporting retaining strips 25 which extend downwardly to points close to thebase frame 1 andserve to prevent the butt ends of the bundles delivered to the shock former, from shifting forwardly undesirable distances. The strip 23 and the parts supported thereby are adapted to be adjusted forwardly or rearwardly by a lever 26 connected, by a link 26, to longitudinally slotted slides 27 to which the strip 23 is secured.

The shaft 5 hereinbefore referred to is provided at one endwith a bevel gear 27 which receives motion, through a gear 28,.

from a short shaft 29 to which is secured a sprocket 30, this sprocket receiving motion, through a chain 31, from the sprocket 13 hereinbefore referred to. i The other end of shaft 5 is connected to a flexible shaft 31 which, in turn, is secured to a clutch member 32 mounted for rotation upon a stem 33 provided at one end with diverging arms 34 each merging into a coil 34. The stem 33 is journaled within a bracket 35 supported pivotally upon a slide 35 mounted on the upper connection 3 and above the throat hereinbefore referred to, there being a fixed arm 36 upon the slide and to which is secured one end of a spring 37, the other end of the spring being connected to the bracket so that said bracket is normally held with the stem 33 inclined downwardly into the space in the upper portion of the shock former. The bracket 35 has an arm 38 extendin therefrom to which is adjustably connected an arm 39 having an integral shoe 40, said shoe being located below and to one side of the twisting coil 34. 'As shown particularly in Fig. 3, arm 39 is pivotally connected to arm 38 at 41 and has a holding bolt 42 shiftable' through any one of the series of apertures 43 so that it is thus possible to adjust the shoe 40 angu- A hook 44 is secured to the arm 39 and is preferably shaped as shown in Figs. 3 and 4, this hook serving to pick up a wisp of material from the bundle passing under the arm 39 and holding it in position to be engaged by the twisting coils 34 as hereinafter pointed out; A knife 45 is secured to the arm 38 so as to cut off any material which might twist about the stem 33.

A disk 46 is feathered on the stem 33 and has a clutch member 47 revoluble therewith. A spring 48 is connected to the disk 46 and serves to hold said disk normally in position with its clutch member 47 out of engagement with the clutch member 32. A lever 49 is fulcrumed on the bracket 35 and is connected by a link 50 to another lever 51 fulcrumed on an arm 52 fixedly mounted on slide 35. A rod 53 connects this lever 51 to an intermediate portion of an actuating lever 54 which is hung from slide 35 and within the throat of the shock former where it will be engaged and elevated by the bundles as they are successively delivered into the shock former. 0bviously each time a bundle passes under lever 54 from the elevator, it elevates said lever 54 until it has cleared the same, and as this lever 54 is raised, motion is transmitted therefrom to the lever 49 which act. to'clamp against the disk 46 and shift it along the stem 33 so as to bring the clutch member 47 into engagement with clutch member 32, this operation serving to couple the flexible shaft 31 to the'stem 33 to cause the stem'33 and twisting coils 34 to rotate. '2

Spring 48 is elongated during this operation and, as soon as lever 54 drops to initial position, spring 48 will return the clutch member 47 to its 1n1t1al position out of engagement with clutch member 32, thus un- 51, to the link 26 and, by a link 52, to

the slide 35. Thus it will be seen that as the strips 25 are pushed forwardly by the lever 26, motion will be transmitted from the link 26 through link 51 to lever 50 which, in turn, will transmit motion through link 52 to the slide 35 which will be automatically centered above the shock being formed.

Mounted on the shaft 5 at desired intervals are eccentrics 55 each of which engages a strap 56 carrying a substantially V-shaped packing finger 57. This packing finger has a depending arm '58 secured to one end of a link 59, the other end of the link being pivotally connected to the extension frame 11. Consequently during the rotation of the shaft 5 and the eccentrics 55, the packing fingers 57 will be caused to rise upwardly back of each bundle elevated and push said bundle inwardly and downwardly within the shockformer and under and past the lever 54. By providing the link 59 in connection with the eccentric 55, the point of each packing finger is given a throwing or clutching action which is very desirable.

The guide rails or standards 3 are movably engaged by grooved wheels 60 carried by yokes 61 which are secured to a side bar 2 62 forming a part of the shock supporter. This bar has an upwardly extending arm 63 at one end which is engaged by a supporting spring 64, this supporting spring being suspended from the upper end portion of one of the standards or guide rails 3. Thusithe bar- 62 is held normally supported close to'but below the throat of the shock former. A supporting finger 63 is fixedly connected to the rear end portion ofthe bar 62 and is extended substantially horizontally from one side to the other of the shock former. Another shock supporting finger 64 is pivotally mounted upon the bar 62 near the front end thereof and is connected, by a yoke 65 to another pivotally mounted finger 66 preferably disposed midway between the fingers 63 and 64. The finger 64 has that end thereof nearest the standard 3 downturned, as at 65, and connected, by spring 66 to a hanger 67 carried by. the bar 62. This spring 66 serves to hold the finger 64 normally horizontal. roller 68 is extended from one side of the finger 64 and is normally overhungv and engaged by the curved arm.69 of a locking lever 7 O which is fulcrumed on a block 71 fixedly connected to the bar 62. A spring 72. connects one arm of this lever 'to'the blockso as to hold the curved end portion of the lever normally in the path of the roller 68. Another roller 73 is mounted in the upper end portion of lever 7 0 and is adapted to be engaged by a roller 74 connected to the free end portion of a latch lever 75 which is fulcrumed preferably on a bracket 76 carried by the block 71. A spring 77 engages the latch lever 75 so as thus to hold the roller 74 normally pressed against lever'70 and the roller 73, thus to hold said lever against movement about its pivot and, consequently, locking the curved arm 69 of lever 70 in the path of roller 68 so that the finger 64 cannot swing downwardly to release the load carried thereby. A dog 78 is pivotally connected to the block 71 and a spring 79 connects this dog to the arm 69 so that, when the roller 68 is held in engagement with the arm 69, the dog 78 is pulled upwardly against the roller as shown. This dog is so proportioned that when arm 69 is swung away from the roller 68, and the said roller is moved out of its normal position, the spring 79 will pull the dog 78 upwardly against the arm 69 so as thus to lock said arm out of the path of the roller 68 and permit said roller to swing back to its normal position without opposition from the arm 69. A bell crank lever 80 is mounted upon one side of the block 71 and one arm of this lever extends under the latch lever 75 while the other arm extends downwardly and is slightlycurved as shown at 81, so that when the shocksupport made up of the bar 62 and the fingers carried thereby is moved downwardly against the action of the supporting springs 64 and under the weight of the load, this arm' 81 W111 iti f mate'ly move against a trip arm' 82"carried p by the base frame 1.

As shown in Fig. 1,'spring retaining fingers 83 are secured to one of the connections 21 and prO ect downwardly between the fingers of the shock supporter when said sup-v As shown in Figs. 1 and 2, a caster may be connected to the outer side of the base 1 of the frame of the shock former, this caster porter is in its normal position, these .retainincluding a stem adjustably mounted in V a block 91 extending outwardly from the side of the frame of the shock former, there i being a set screw 92 in the block for engaging the stem to hold the stemagainst movement. This caster is to be attached tov the machine when the shock former is uncoupled from the harvester and is to be moved from place to place. At other times the caster can be removed.

As the bundles of material to be formed into a shock are delivered from the binding mechanism, they are engaged by the fingers 8 of the elevator, and carried upwardly to the throat of the shock former. 'Eacli bundle as it passes through the throat of the machine'is carried under and actuates the lever 54, the packing fingers 57 servingto thrust thebundles into the shock former and onto the supporting fingers 64, 66 and 63. As each bundle passes under the lever 54 and raises it, the stem 33 isccupled to the continuously rotating flexible shaft 31 so that the twisting coils 34 will thus be brought into action. The bundle in passing under the shoe 40 is engaged by the hook 44 which pulls a wisp from the bundle and holds it where it will be engaged by the twisting coils 34. This wisp remains in engagement with the coils and is twisted with a wisp from the next following bundle. As the bundles are thus discharged into the shock former they are all tied together by the mechanism described, it being apparent that the shoe 40 always holds the coils 34 the proper distance from the top of the bundle, upward and downward swinging movement of the coil and shoe being permitted without necessarily throwing the clutch member 47 into engagement with the clutch member 32.

As the various bundles are tied together and new-bundles admitted to the shock former,

the weight supported by the fingers 63,, 64

- along the guide standards 3 until the arm 81 V ings butts of the bundles.

of bell crank lever 80 strikes the stationary arm or bracket 82 whereupon the latch lever 7 5'is elevated out of the path of roller 73 and the roller 68 pushes upwardly against the curved arm 69 (see Fig. 6) sothat the two fingers 6% and 66 are thus free to swing downwardly. During the downward move ment of the fingers the spring 79 pulls on the dog 78 which is brought to position against the arm 69 and locks the lever 70 elevated against the action of its spring 72, as shown by dotted lines in Fig. 6. \Vhen the fingers 64 and 66 swing downwardly under the weight of the load carried thereby, the butt ends of the bundles forming the shock and which are at the front of the machine, will drop downwardly onto a lever 8-1 which extends under the front portion of the base frame 1 and in the path of the depend- The outer end of this lever is connected by a rod 85 to an ejecting lever 86 extending over the front portion of the shock former. Consequently when lever St is moved downwardly by the and 63 are relieved of the weight of the shock and are promptly returned to elevated positions by the springs 64c this upward movement of the fingers 63, combined with the forward movement of the shock former,

serving to swing the deposited shock to an upright position with its butt end on the ground. A spring 87 returns the levers 84:

I and 86 to their initial positions after the ejection of the shock.

As soon as the fingers 6i and 66 are relieved of the weight of the shock, the spring 66 returns them to their initial positions so that the roller 68 will strike against dog 78 and move it out of engagement with arm 69, thus allowing the spring 7 2 to swing said arm 69 to normal or locking position, while at the same time spring 77 will swing the latch lever downwardly into locking position as shown in full lines in Fig. 6. Thus the parts are all reset to repeat the operation described. An adjustable stop 74: can be provided for limiting the downward movement of the arm 75.
